Bunch of computers participating in a blockchain network.
A network can be public (anyone can participate like in the Ethereum blockchain) or private.
Types of nodes:
- Miner; Creating new blocks
- Full node; Checking block validity using all transactions and blocks.
- Lightweight node; Checking chain integrity using only the block headers.
In a private network you don need mining, you can just appoint one or more node that can create new blocks.
